Yes, my way is what old timers do (I have been urban cycling for 30 years) but we are a tiny minority and the rest of the commuters just use whatever clothes are their daily standard, with maybe a slight adaptation... Still I don't understand how they are comfortable in any but mild weather conditions: specialized cycling clothing is so much more comfortable in heat, storms, snow and anything in-between - and I most people in the office have no idea I commute by bicycle (though they may suspect it when they contemplate my gorgeous ass)...
